CLOUD FOREST OBSERVATORY

JAN–JUNE 2026 | KAʻŪ, HAWAIʻI | 4,500–4,600 FT

Earthstar fungus emerging from native cloud forest floor following moisture event within Koa Cloud Forest Conservancy ecosystem

MAY 1, 2026 - 9:00 AM | ~4,550 FT

(KCFC)

OBSERVATION

Earthstar fungi (likely Geastrum spp.; family Geastraceae) identified approximately 2 ft below the soil surface, with multiple developmental stages present. Hygroscopic outer rays had reflexed outward, elevating the central spore sac above saturated soil layers. Specimens appeared positioned for imminent spore dispersal, potentially triggered by continued moisture input or raindrop impact.

INTERPRETATION

These observations are consistent with active fungal decomposition and conditions that may support mycorrhizal activity within saturated subsurface microhabitats.

Native cloud forest fungi contributing to decomposition and nutrient cycling within Koa Cloud Forest Conservancy ecosystem

MAY 29, 2026 - 5:09 PM | ~4,510 FT

(KCFC)

OBSERVATION

Standing dead koa (Acacia koa) monitored through fungal colonization and progressive wood decomposition. An ʻōhiʻa (Metrosideros polymorpha) seedling was documented emerging from a natural bifurcation within the decomposing parent tree alongside ongoing koa regeneration.

INTERPRETATION

Illustrates how decomposing trees create favorable microhabitats for native species recruitment. The coexistence of koa, ʻōhiʻa, and fungal communities reflects interconnected regeneration processes that support long-term forest resilience.

Naturally regenerating Acacia koa seedling emerging from compacted forest substrate following natural disturbance in Hawaiʻi cloud forest habitat

MARCH 30, 2026 - 1:25 PM | ~4,500 FT (KCFC)

OBSERVATION

Koa (Acacia koa) seedling emerging within a primary disturbed pathway beneath low-light cloud forest canopy conditions. Consistent vertical growth observed following emergence.

INTERPRETATION

Indicates successful koa establishment within compacted pathway soils, with observed phototropic growth and leaflet movement consistent with continued physiological function beneath dense montane cloud forest canopy cover.

OBSERVATION

Earthstar fungi (likely Geastrum spp.; family Geastraceae) identified approximately 2 ft below the soil surface, with multiple developmental stages present. Hygroscopic outer rays had reflexed outward, elevating the central spore sac above saturated soil layers. Specimens appeared positioned for imminent spore dispersal, potentially triggered by continued moisture input or raindrop impact.

INTERPRETATION

Reflects active fungal decomposition and probable mycorrhizal activity within saturated subsurface microhabitats, with hygroscopic dispersal structures responding dynamically to elevated moisture availability.
